Ukusetyenziswa kwee-inoculants ze-ferrosilicon: Okwangoku, ii-camshafts zepetroli kunye neenjini ze-diesel zenziwe ngentsimbi, i-alloy cast iron, kunye ne-ductile iron, kwaye zisebenzisa iinkqubo zokucima okanye ukutshatyalaliswa okubandayo (inkqubo ye-alloy cast iron) ukuhlangabezana neemfuno ezibanzi zokusebenza.Nangona kunjalo, i-shafts yentsimbi kunye ne-ductile shafts ye-iron ayifanelekanga kwiinjini ze-high-speed ezingaphezu kwe-4000 rpm, kwaye amandla e-alloy alloy cast iron cast ayifanelekanga kwiimfuno zamandla zeenjini eziphakathi.
Umsebenzi we-inoculant ye-ferrosilicon kukoyisa itekhnoloji ekhoyo yentsimbi okanye i-ductile iron material ayifanelekanga kwiimfuno ezichasene nokunxitywa kweenjini ezinesantya esiphezulu kunye ne-cold-shock-shock alloy cast iron material ayifanelekanga kwiimfuno zamandla aphakathi. kunye neenjini ezinesantya esiphantsi, kwaye ibonelela ngendlela efanelekileyo kuzo zonke iintlobo zeenjini.I-cold-shock alloy ductile iron kunye necamshaft casting method ehlangabezana neemfuno zokungagugi kwe-injini, ukumelana nomkrwelo, ukuxhathisa kwe-spalling, indawo yokudinwa amandla omatshini wokudinwa, njl njl. ukonga amandla.I-inoculant ye-ferrosilicon ithatha i-random-dose inoculation ye-dose enkulu, kwaye umxholo we-silicon iyonke yi-1.9% -3.7%.Uvavanyo lwangaphambili lwesithando somlilo lubonisa ukulingana kwekhabhoni yentsimbi yokuqala eshushu, i-carbon elingana ne-nodularizing agent (ukuhlolwa kwangempela kwexabiso elivuthayo) kunye nekhabhoni elingana ne-ferrosilicon inoculant (Inani elipheleleyo lokufunxa liphakathi kwe-4.3-4.55. inyibilika kwi-frequency yamandla okanye i-intermediate frequency furnace, kwaye iqondo lokushisa lomlilo liyi-1450 ° C. Indlela yokuphosa i-camshaft ye-cold-shock alloy ductile iron kukubumba kwesanti eluhlaza, ukuphosa okumanzi, kunye nokufuma kwesanti yokubumba kungaphantsi kwe-4%; ubushushu bokugalela yi-1340-1360 ° C, ubukhulu bentsimbi yokupholisa yangaphandle yi-0.25-0.4 yobubanzi obungaphandle bepesika yecam, kunye nobubanzi bentsimbi yokupholisa yangaphandle Ububanzi obufanayo nepesika yecam. intsimbi yokupholisa yangaphandle ubukhulu be-radial ye-cam peach emva kokuhlukana + amaxesha ama-2 ubukhulu bentsimbi ebandayo Umngxuma ongaphakathi wentsimbi yokupholisa yangaphandle yeyona ndawo yobukhulu be-radial yecala lebhokisi ye-peach ye-cam + 2mm kwelinye icala. I-periphery ingaba nayiphi na imilo, kunye ne-slope ye-1-2 ° ukusuka ezantsi ukuya phezulu.
